Abstract

Purpose: This study was performed to determine vertical fixation disparity by Fixation Disparity Card. The purpose of this study was to investigate distribution of the curve types obtained with Wesson card. Methods: Fixation disparity curves were measured on 52 subjects with the Wesson fixation disparity card. A fixation disparity curve was an x, y coordinate plot of the angular amount of fixation disparity as a function of the power of prisms through which the patient views. The fixation disparity curve variables that were used to aid in the diagnosis and management of binocular vision disorders included the x-intercept, y-intercept, curve slope and curve type. Results: Vertical fixation disparity curves by Wesson Fixation Disparity Card were very various. Conclusions: Vertiical fixation disparity curves could be used to aid in the diagnosis and prescription.

목적: 주시시차 카드를 이용하여 수직주시시차를 측정하였다. 이 연구의 목적은 Wesson 주기시차카드를 이용한 주시시차 검사법에 의해 수직주시시차의 분포를 조사하고, 진단과 처방에 응용하는데 있다. 방법: Wesson 주시시차 카드를 이용하여 52명을 대상으로 수직주시시차를 측정하였다. 주시시차곡선은 추가한 프리즘량과 주시시차량에 대한 함수이며, 주시시차 곡선에서 진단과 처방에 사용되는 값은 x-절편, y-절편, 기울기, 곡선 타입이다. 결과: Wesson 주시시차 카드를 이용한 두시시차 측정 결과 여러 가지 type의 수직주시시차 곡선을 얻을 수 있었다. 결론: 수직주시시차 곡선을 진단과 처방에 이용할 수 있다.
